Ron placed a grilled cheese sandwich, a sneaker, a pinecone, and a dog collar together on a scale. the sandwich weighs 0.462 lb, the sneaker weighs 290.87 g, the pinecone weighs 0.453 ton, and the dog collar weighs 0.246 kg. there are 2.20462 pounds in one kilogram. how many ounces do all of these objects weigh in total

27.7791 oz

Step-by-step explanation:

The conversion of lb into ounces is shown below as:

1 lb = 16 oz

So, Sandwich weight = 0.462 lb = 7.392 oz

The conversion of g into ounces is shown below as:

1 g = 1/28.35 oz

So, sneaker weight = 290.87 g = 10.2601 oz

The conversion of ton into ounces is shown below as:

1 ton = 1/32000  oz

So, pinecone weight = 0.0000453 ton = 1.4496 oz

The conversion of kg into ounces is shown below as:

1 kg = 35.274  oz

So, sneaker weight = 0.246 kg = 8.6774 oz

Total weight = 7.392 oz + 10.2601 oz + 1.4496 oz + 8.6774 oz = 27.7791 oz

450 is the final answer! : )
